Prerequisites

• I verified that this is not a filter issue
  • Filter issues MUST be reported at filter issue tracker
• This is not a support issue or a question
  • Support issues and questions are handled at /r/uBlockOrigin
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue
  • Your issue may already be reported.
• I tried to reproduce the issue when...
  • uBlock Origin is the only extension
  • uBlock Origin with default lists/settings
  • using a new, unmodified browser profile
• I am running the latest version of uBlock Origin
• I checked the documentation to understand that the issue I report is not a normal behavior

Description

Tooltip text in popup panel says about "Local rules" and "overriding them". There is nothing like this when "I am an advanced user" is not enabled.

A specific URL where the issue occurs

Popup interface

Steps to Reproduce

1. Open UBO popup panel
2. Unfold dynamic filtering panel if not visible
3. Hover mouse over first row, second column of dynamic filtering interface

Expected behavior:

I will expect to see tooltip with text like this:

The cells in the third column gives an overview of how many requests were blocked/allowed:

    - or + = between 1-9 network requests were blocked or allowed, respectively
    -- or ++ = between 10-99 network requests were blocked or allowed, respectively
    --- or +++ = 100 or more network requests were blocked or allowed, respectively
    blank cell = no network requests occurred for the specific hostname

Actual behavior:

Your environment

• uBlock Origin version: 1.16.1rc4, 1.16.0
• Browser Name and version: Firefox Nightly 20180424100107, Firefox beta
• Operating System and version: Mint 18.3

For me, uBO's tooltips has always been a mess.
No matter where I place the cursor, I get a popup that simply says "uBlock Origin".
..and if a real tooltip is present, that popup is placed on top of it:

• uBlock Origin version: 1.16.0
• Browser Name and version: Pale Moon v27.9.0 (x64)
• Operating System and version: Windows 8.1 Pro (x64)

EDIT:
I was able to prevent this behaviour, by setting browser.chrome.toolbar_tips to false, in Pale Moon's about:config

That is a Firefox legacy-only issue.

Would it be possible to fix this issue in uBO, e.g. by adding a code that prevents the legacy builds from being affected by browser-side tooltips?
